The Quebec labour market of the last two decades has undergone profound changes due to progress in information technology and market globalization. This new context has generated new forms of work which have been termed” non-standard work”. Since the early eighties, the number of such positions has been growing significantly. Often associated with precarious employment activity, the phenomenon of non-standard work has raised a fundamental question: are these positions stable? This is the main question that we wish to investigate from the perspective of new immigrants: do new immigrants achieve stability in the labour market upon arrival in Quebec? In a society that has, quite often for demographic and economic reasons, welcomed an average of 35,000 newcomers every year since the early 90s, the success (or failure) of economic integration rests in part on immigrants’ capacity to participate in the labour market and remain employed. Our analysis is based on a longitudinal survey that describes the biographical trajectories of the Settlement of New Immigrants (SNI). This survey describes the main attempts of 1,000 immigrants’ to establish themselves over a period of 10 years in the greater Montreal area. This research mainly shows that continuous sequences of employment are growing overtime, thus ensuring new immigrants greater stability in the labour market. On the other hand, results suggest that racial discrimination modulates labour market participation, in particular for natives of North Africa and the Middle East.  相似文献

Objective: The aim of the present study was to compare autonomic activity, pressure-pain thresholds, and subjective assessments of health and behavior between patients with stress-related illnesses and healthy control subjects.Methods: Twenty sick-listed patients with stress-related illnesses and 20 age- and gender-matched healthy subjects performed tests of autonomic regulation and algometric tests, and completed questionnaires about physical and mental health and behavioral patterns.Results: Patients exhibited higher autonomic reactivity to cognitive and physical laboratory tasks (p<0.05), and had lower pressure-pain thresholds in the shoulders and lower back than healthy control subjects (p<0.05). Furthermore, the patients rated considerably poorer health and health behavior than the control subjects (p<0.05).Conclusions: The results indicate an engagement of the autonomic nervous system in stress-related illnesses. Furthermore, they show that patients with stress-related illnesses experience symptoms of musculoskeletal pain, and it is therefore recommended that assessments of musculoskeletal pain be incorporated in the clinical examinations and the rehabilitation of patients with stress-related illnesses.  相似文献

Objective: Although there is some evidence of the association between specific food groups, such as plant foods, and subjective wellbeing, this is the first study to assess the relationship between adherence to the Mediterranean dietary pattern and subjective wellbeing. Design: Data were collected in 2014–2015, within the Edad con Salud project, a follow-up study of a multistage clustered survey on a representative sample of the population of Spain. The final sample comprised 2397 individuals with ages ranging from 21 to 101 years. Main outcome measures: Experienced wellbeing (positive and negative affect) was measured using the Day Reconstruction Method, and evaluative wellbeing was assessed with the Cantril Self-Anchoring Striving Scale. Results: A higher adherence to the Mediterranean diet showed a small but statistically significant inverse relationship with negative affect (β?=??0.076, p=.001), and direct with evaluative wellbeing (β?=?0.053, p=.015), whereas it was not related to positive affect. Several components of the Mediterranean diet were independently associated with wellbeing. Conclusion: The results suggest that adherence to a dietary pattern such as the Mediterranean diet, and not only the isolated consumption of its components, is associated with a better subjective wellbeing.  相似文献

This study analyzes the psychometric and structural properties of the BSI-18 in a sample of Spanish outpatients with psychiatric disorders (N = 200), with three basic objectives: (a) to study the structural validity of the instrument; (b) to analyse reliability (internal consistency and test-retest stability) and validity (convergent and discriminant) of the instrument, and (c) to evaluate sensitivity to change in a therapeutic context. Using confirmatory factor analysis, two models were tested: the three-dimensional theoretical model proposed by its authors, and the empirical four-factor model obtained by the same authors through exploratory factor analysis. Our results showed that the best structure was a four-dimensional model, with the General Distress index and Somatization, Depression, General Anxiety and Panic scores. These four scales showed good internal consistency, test-retest reliability, validity and sensitivity to therapeutic change. The BSI-18 has been shown to be a reliable and useful tool for psychiatric assessment of patients, with the added advantage provided by its simplicity and ease of application.  相似文献

The current paper proposes a solution that generalizes ideas of Brown and Forsythe to the problem of comparing hypotheses in two-way classification designs with heteroscedastic error structure. Unlike the standard analysis of variance, the proposed approach does not require the homogeneity assumption. A comprehensive simulation study, in which sample size of the cells, relationship between the cell sizes and unequal variance, degree of variance heterogeneity, and population distribution shape were systematically manipulated, shows that the proposed approximation was generally robust when normality and heterogeneity were jointly violated.  相似文献

The goal of this study is to validate a Spanish version of the Physical Activity Enjoyment Scale (PACES, Kendzierski & DeCarlo, 1991), in the population of Spanish adolescent girls, and also to obtain a reduced version of the scale. For this purpose, reliability analysis was conducted, and construct validity was assessed in two steps: exploratory factor analysis and structural equation model with confirmatory factor analysis. The scale was administered to a sample of 2777 adolescent girls of Secondary Education, ages between 12-18 years. The results show the reliability of the instrument and the construct validity with a good fit of the model. The adapted scale was reduced to six items, a shorter and efficient scale that allows us to measure the enjoyment of physical activity.  相似文献

The present study aims to determine the relationship among factors that make up the parenting styles according to the PCRI (Parent-Child Relationship Inventory) and hyperactivity reported by parents through the BASC (Behaviour Assessment System for Children). We selected a sample of 32 children between 3 and 14 years old (23 male and 9 female) with risk scores in hyperactivity and another similar group with low scores in hyperactivity. After administering both instruments to the parents, we carried out a binomial logistic regression analysis which resulted in a prediction model for 84.4% of the sample, made up of the PCRI factors: fathers' involvement, communication and role orientation, mothers' parental support, and both parents' limit-setting and autonomy. Moreover, our analysis of the variance produced significant differences in the support perceived by the fathers and mothers of both groups. Lastly, the utility of results to propose intervention strategies within the family based on an authoritative style is discussed.  相似文献

Combining two different samples of cocaine users (N = 183), we tested the factor structure of a brief (12-item), Spanish version of the Cocaine Craving Questionnaire-General using confirmatory factor analysis. The four-factor model provided excellent fit to the measure. Moreover, the measure significantly differentiated between recent cocaine users and abstainers, as well as between participants with different levels of severity of drug-use history. Factor 1 expresses highly intense and overwhelming desires, Factor 2 expresses lack of self-control over cocaine use, Factor 3 items express lack of positive reinforcement expectancies, and Factor 4 expresses stimulating expectancies for cocaine use. The results revealed the validity of the CCQ-General brief as an instrument to assess cocaine craving in Spanish and supported the conceptualization of cocaine craving as a multifaceted construct.  相似文献

A fine-grained dual-process approach to conditional reasoning is advocated: Responses to conditional syllogisms are reached through the operation of either one of two systems, each of which can rely on two different mechanisms. System1 relies either on pragmatic implicatures or on the retrieval of information from semantic memory; System2 operates first through inhibition of System1, then (but not always) through activation of analytical processes. It follows that reasoners will fall into one of four groups of increasing reasoning ability, each group being uniquely characterized by (a) the modal pattern of individual answers to blocks of affirming the consequent (AC), denying the antecedent (DA), and modus tollens (MT) syllogisms featuring the same conditional; and (b) the average rate of determinate answers to AC, DA, and MT. This account receives indirect support from the extant literature and direct support from a mixed Rasch model of responses given to 18 syllogisms by 486 adult reasoners.  相似文献
